So needs a bit of work, but is doable and would be a great addition,
since we do support:

# perf top --group -e instructions,cycles,cache-misses

And we should strive to make 'perf top' to be a perf.data-less, dynamic
version of 'perf record + perf report'.

Can you please take a look at supporting this? And that --group-sort-idx
too,

I'll push my perf/core branch after a few tests,

Thanks,

- Arnaldo
